Jimmy Herget’s uneven season raises questions beyond his 5.70 ERA

Purple Row ranked Colorado Rockies relief pitcher Jimmy Herget at No. 26 in its 2026 season review series based on his 0.1 rWAR. Herget posted a 0-6 record with a 5.70 ERA and a 1.53 WHIP across 51 appearances in 2026, a significant drop from his 2.48 ERA in 2025. The writer notes Herget endured two severe slumps that inflated his ERA despite performing well across his other 46.1 innings.

Herget's campaign was disrupted by off-field events, including paternity leave, bereavement leave, and an injured list stint for a shoulder impingement. James Riggenbach highlights that Herget introduced a cutter and initially abandoned his slider, which struggled against left-handed hitters before he brought the slider back in late August.
